Wind-hole base of a blower for an air conditioner

ABSTRACT

A wind-hole base of a blower for an air conditioner includes a faceplate, a cover plate, two fix plates, and two wind outlet cases. The faceplate has two outlets and an inlet, and a connector respectively fixed at two sides of the inlet. The two cover plates have a wind hole on the inlet, and the fix plates are mounted on a steel frame fixed on a ceiling, screwed with the connector of the faceplate. The wind outlet cases are fixed on the two outlets and have a wind hole connected with a windpipe. Thus the wind-hole base have two functions of sending wind out and sucking wind in, and possible to be assembled with the fix plates screwed with the steel frame so that the wind-hole base may be easily and quickly assembled and adjusted to move its position.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to a wind-hole base of a blower for an airconditioner, particularly to one possible to be combined quickly with aceiling, having two outlets and an inlet so as to facilitate check andrepair the wind-hole base when necessary.

[0003] 2. Description of the Prior Art

[0004] A conventional wind-hole base 8 for a central air conditionershown in FIGS. 1 and 2, uses windpipes 81 connected to a main machine tocirculate cool air and retrieve hot wind back. And an outlet 82 or aninlet 83 is provided at an end exit of each windpipe 81, performing aircirculation to every room at the same time. Each room may have a steelframe 6 fixed on the ceiling for mounting the outlet 82 and the inlet 83thereon. So the more the outlets 82 and the inlets are provided, themore the steel frames 6 have to be provided, complicating constructingprocesses and subsequent difficulty involved in maintenance and repairafter they are finished.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0014] A preferred embodiment of a wind-hole base of a blower for an airconditioner in the present invention, as shown in FIGS. 3, 4 and 5,includes a faceplate 1, a cover plate 2, two fix plates 3, and two windoutlet cases 4 as main components combined together.

[0015] The faceplate 1 has an outlet 10 provided respectively in twolengthwise opposite sides, wind guiding leaves adjustably fitted insideeach outlet 10, plural combine holes 100 bored in a lengthwise wall, aninlet 11 formed in an intermediate portion, plural insert grooves 110(FIG. 4 also referred) and engage holes 111 formed at diverse positionsin an inner wall defining the inlet 11, link holes 112 of differentshapes (such as rectangular, circular, etc.) provided in acircumferential edge of the inlet 11, a lengthwise grid plate 12 fixedto close on the inlet 11, and a filter net 13 positioned between theinlet opening 11 and the grid plate 12. The grid plate 12 has insertprojections 120 extending outward from a lengthwise side, and so doesthe filter net 13 have insert projections 130, as shown in FIGS. 3 and5. Further, an elongate connector 14 is respectively fixed on twolengthwise opposite sides of the faceplate with screws 7, having athreaded rod 140 extending upward.

[0016] The cover plate 2 is combined on the inlet 11 of the faceplate 1,shaped as an inverted case, having circumferential lip edges 20 to fitclosely in an inner circumferential edge of the inlet 11 of thefaceplate 1, plural insert projections 21 extending out from alengthwise side to fit in the insert grooves 110 of the inlet opening11, plural engage blocks 22 formed to extend down from the otherlengthwise side and plural posts 23 each with a center screw hole formeddownward near the relative engage blocks 22 to fit in the link holes 112of the inlet 11 or screwed together with the faceplate 1 with screws 7.Besides, the cover plate 2 has plural outlet holes 24 spaced apart forconnecting windpipes 5.

[0017] The two elongate fix plates 3 are fixed across on the steel frame6 mounted on the ceiling, combined with the connectors 14 of thefaceplate 1, having an elongate slot 30 respectively in two end portionsfor the threaded rod 140 to pass through to adjust their own position,fixed with screws 31 in place, and in addition, the screws 31 can adjustthe gap between the faceplate 1 and the steel frame 6 as well.

[0018] The two wind outlet cases 4 are fixed respectively to close up onthe two outlets 10 of the faceplate 1 by means of screws 7, having asurrounding wall of a certain thickness and height and made of heatinsulating material (for example, foam) to keep inner temperature, arectangular opening 41 formed in a bottom side, plural combine holes 42bored in the wall around the opening 41 and screwed with the combineholes 100 of each outlet 10. Further, a circular outlet hole 43 isformed in an intermediate portion of each wind outlet case 4, and aconnect member 44 is provided to combine with the wall around the outlethole 43 for easily connecting with a wind pipe 5, having a fix plate 440bored with plural screw holes 441 at an inner side so as to fix theconnect member 44 with the wind outlet case 4 with screws 7. Further,the connect base 44 has many elastic plates 442 formed in an outer endof the two sides, and each elastic plate 442 has a projecting insertedge 443 to connect with the wind pipe 5 easily.

[0019] In assembling, referring to FIGS. 3-6, firstly fix the coverplate 2 in the inlet 11 of the faceplate 1, with the insert blocks 21inserting in the insert grooves 110 of the faceplate 1, and with theengage blocks 22 inserting in the link holes 112 of the inlet opening 11as shown in FIG. 5. Or the posts 23 with a center screw hole are made topass through the link holes 112 and then screwed from under with screws7 to fix the cover 2 with the faceplate 1. Next, the grid plate 12 andthe filter net 13 are combined firmly under the inlet II with the insertprojections 120 and 130 fitting in the insert grooves 110 and engageholes 111. Then the wind outlet cases 4 are screwed on the outlets 10 ofthe faceplate 1. When the wind-hole base is to be mounted on a ceiling,the two elongate plates 3 are placed across the steel frame 6, as shownin FIGS. 3 and 4, and then the threaded rods 140 of the connector 14 aremade to pass through the elongate slots 30, and fixed firmly with thescrews 31. Next, the wind pipes 5 are connected to the connect member 44of the wind outlet cases 4 and the outlet holes 20 of the cover plate 2,finishing assembly of the wind-hole base either for sending wind out orsucking wind in, as shown in FIGS. 5 and 6.

[0020] Provided the wind-hole base or the wind pipes have to be checkedor repaired, first remove the grid plate 12 and the filter net 13, andpush open the cover 2 by pricking the engage blocks 22 off the insertgrooves 110 or loosen the screws off the post 23. Now a worker can gothrough the inlet 12 in the wind-hole base for check or repair. Or aworker can adjust the location of the connectors 14 connecting theelongate fix plates 3 and the faceplate 1. Thus, maintenance or repaircan be carried out easily.

[0021] The invention has the following advantages as can be understoodfrom the aforesaid description.

[0022] 1. Its assembly can be performed quickly and easily

[0023] 2. It has a structure of both wind sending-out and sucking-in.

[0024] 3. Its maintenance or repair may be carried out with convenience.

[0025] 4. The faceplate can be adjusted vertically in the gap againstthe ceiling (or the steel frame) and also moved laterally by means ofthe connector and the fix frame with screws to alter its location ifnecessary.
